What is the area of the trapezoid

Answer:

61

Step-by-step explanation:

90 divided by 36 is 2.5 add 10 to the 90 then multiply 10 by 2.5 you get 25 then add 25 to 36 witch gives u 61.  90/36=2.5x10=25+36=61

/ is for division. Hope it helps.

Answer:

Age

Step-by-step explanation:

it is about them.

If it were how many siblings they have it, then would not be just about them.

If it were there sport it would not be about them it would also be about sports

Answer:

a. 88.70% of the variation in the cost is being explained by the resolution.

Step-by-step explanation:

Given :

Summation of (Yi - Ybar)2 = 147172

Summation of (Yhat - Ybar)2 = 130542

Summation of (Y - Yhat)2 = 16630

The Coefficient of determination (R²) :

Sum of Square regression (SSR) / sum of square TOTAL (SST). It gives the percentage of the dependent variable which can be explained by the regression line.

Cost is the dependent variable in this scenario.

SSR = Summation of (Yhat - Ybar)2 = 130542

SST = Summation of (Yi - Ybar)2 = 147172

Hence,

SSR / SST = 130542 / 147172

R² = 130542 / 147172

R² = 0.8870029 = (0.8870029 * 100%) = 88.7%

Answer:

10.4

Step-by-step explanation:

So let's do the basic, adding. 5 kilometers on Saturday and 4 on part of Sunday. That's 9. So let's save that. Now for the meters. We know that there are 1000 meters in a kilometer. So add up 600 and 800. That gives you 1400 meters total. Now if we divide 1400 by 1000, we get 1.4. So that is how many kilometers he rode on Friday and and the other part of Sunday. SO now we just add everthing up. 9km+1.4km = 10.4, your answer

Answer:

2.34 cm

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle at the centre (θ) = 34°

Radius (r) = 4 cm

Length of chord (C) =?

The length of the chord can be obtained as follow:

C = 2rSine(θ/2)

C = 2 × 4 × Sine(34/2)

C = 8 × Sine 17

C = 8 × 0.2924

C = 2.34 cm

Therefore, the lenght of the chord is 2.34 cm.

For this question the answer is:

C.

Answer:

137°

Step-by-step explanation:

ACD = ACB+BCD

ACD= 75°+62°= 137°

Answer:

Angle ACD = ANGLE ACB + BCD

=75°+62

= 137°

Answer:

The above calculator compounds interest monthly after each deposit is made. Deposits are applied at the beginning of each month. If you want to make deposits at the end of each month, then please subtract the first deposit from the initial savings amount.

Step-by-step explanation:

Answer:

a = 0.3

b = 0.4

c = 40%

d = 15%

Step-by-step explanation:

There are a total of 10 tick marks. So we know that 1 tick mark = 10%

a has 3 tick marks so you can say it's 0.3

b has 4 tick marks so you can say it's 0.4

c also has 4 tick marks, but it's asking for the percentage, so you get 40%

d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%

Answer:

false

Step-by-step explanation:

Answer:

so um your answer is in step by step

Step-by-step explanation:

I assume you just want to calculate the cost of making a circle with a diameter of 2.5 feet.

The area of a circle can be calculated using the following formula:   A = pi * r2

The radius of a circle is half of the diameter.  For this problem, the radius will be 2.5 / 2 or 1.25 feet and pi is 3.14

Then the area will be :  A= 3.14 * 1.252

A= 3.14 * 1.5625 = 4.90625 ft2

If each square foot cost $32.50, then the wood will cost $32.50 * 4.90625 = $159.45

Your answer is:

V(n) = 30(0.95)^n

Why?

Well here is why!

Rate of decrease = 5%

Period, n = 10 days

Initial stock price = $30

Value of share price as a function of n:

Value, V(n)

Initial price = A

V(n) = Initial price(1 - rate)^n

V(n) = 30(1 - 0.05)^n

V(n) = 30(0.95)^n

Answer:

26

Step-by-step explanation:

first, substitute the value for x into the expression. since x = 6, you will be plugging in 6 for x.

4x + 2 ⇒ 4(6) + 2

simplify the expression, starting with 4 · 6.

4(6) + 2 ⇒ 24 + 2

then add 24 + 2.

24 + 2 ⇒ 26

aaaand your answer is 26! hope this helps. have a lovely day! <3

Answer:

a) 0.1769 = 17.69% probability that both professors get their grants funded.

b) 0.7231 = 72.31% probability that at least one of the professors will be funded.

c) 0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.

d) 0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not

Step-by-step explanation:

a. What is the probability that both professors get their grants funded?

Jane has a 0.61 probability of being funded.

Joe has a 0.29 probability of being funded.

So

[tex]p = 0.61*0.29 = 0.1769[/tex]

0.1769 = 17.69% probability that both professors get their grants funded.

b. What is the probability that at least one of the professors will be funded?

None:

Jane has a 1 - 0.61 = 0.39 probability of not being funded.

Joe has a 1 - 0.29 = 0.71 probability of not being funded.

0.39*0.71 = 0.2769

At least one:

1 - 0.2769 = 0.7231

0.7231 = 72.31% probability that at least one of the professors will be funded.

c. What is the probability that Professor Jane is funded but Professor Joe is not?

Jane has a 0.61 probability of being funded.

Joe has a 1 - 0.29 = 0.71 probability of not being funded.

0.61*0.71 = 0.4331

0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.

d. Given at least one of the professors is funded, what is the probability that Professor Jane is funded but Professor Joe is not?

0.4331/0.7231 = 0.5989

0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not
